When the A/C is turned on my 1994 C220 the A/C fans don't come on at all. I first thought the engine wasn't hot enough so I let it run for a while and the engine got very warm under load and A/C..but still no fans (and no overheating/boil over thank god).

First think to check is the fuses and relay. Except I can't find them! A previous post said "There is a relay that is located under the top side of the fuse box. "...Can someone give me a more specific location in which to look?

Any other ideas/tests? I remember on My 190E you could get the fans to run by connecting two leads near the A/C evaporator (pressure switch?). Is there something similar in the C220?

Many Thanks,
Chandra
